Contribution to the study of soils of the Pico Sacro (Santiago)

Soil types and distribution in the Pico Sacro region are governed by parent materials and topography. Soils over quartz substratum tend to become podzolized, with marked losses of elements in the upper horizons and their redistribution in the lower horizons. Soils over amphibolitic material tend to evolve towards brown earths under well drained conditions and towards histosols, with accumulation of organic matter, under impeded drainage.
